IEEE Std 802-2001 specifies the second shown form (with hyphens)
|

as the canonical form for MAC addresses, and specifies the first
|

form (with colons) as the bit-reversed notation, so that
|
||||
08-00-2b-01-02-03 = 01:00:4D:08:04:0C. This convention is widely
|
||||
ignored nowadays, and it is only relevant for obsolete network
|
||||
protocols (such as Token Ring). PostgreSQL makes no provisions
|
||||
for bit reversal, and all accepted formats use the canonical LSB
|

order.
